Wordpress help

How do i turn on the permalink and how do i direct users back to my blog with wordpress?

I'm not sure where you're heading, but you change the permalinks in settings/permalinks.

The second part of the sentence is confusing. Please elaborate.

Hey Permalink can be changed by settings<Permalink

Though if you changing from one permalink to another and already posted few posts, I will suggest use this plugin :
